How I Use It
Besides teachers taking personal notes, you can organize reading or writing conferences with kids. In our district, teachers use this for conferring notes instead of having binders for all kids. Then they have the notes at school and home when making goals for their students. This is especially helpful when students are conferring with the classroom teacher and a reading specialist. Both teachers have access to each other's notes.
Evernote is a great way to easily organize notes from different staff and team meetings and then share notes with each other. We often see articles we want to read but don't have time at the moment. With Evernote you can clip them and save directly to notebooks for future access. I have never lost anything. You can add multiple tags to search by keyword and find a note months later.
